Hi,
I have a mk4 golf, 150pd an it has a loss of power. Throttle response seems very slow an sluggish an boost wouldn't be great either. I've changed the map sensor as it was giving a constant reading of 255kpa so thought it was it an no joy, it's still giving the same reading. My mpg is really bad to an it's killing me, as it's not showing any faults. Please can anyone help me?
